Fischer increment adds a fixed amount of time to a player's clock after each completed move. For example, a 10+5 control gives each player ten minutes at the start and adds five seconds after every move. The extra time is added even when a player moves immediately. It is a good choice when you want fast games to remain playable in the final moves without turning every ending into a race to tap the screen.
Open the Fischer settings
From the 1Chess Clock home screen, open the game settings and select Fischer increment. Enter the base time first, then enter the increment in seconds. Check both values on the confirmation screen before returning to the clock. A useful test setup is 5+3 or 10+5: both make the added time easy to see after a move.
Do not confuse increment with delay. With Fischer, the increment is credited after every completed move, so a player can slowly build time if they move faster than the increment. If your event uses a grace period instead, read how to set Bronstein delay before you begin.
Save and test the preset
Save the configuration, then run a short test. Start the clock, wait a few seconds, and tap the active player's side. Their displayed time should increase by the amount you entered, after accounting for the time used on that move. Repeat from the other side so both players understand what they will see.
For a normal over-the-board game, place the phone where neither player must reach across the board. The clock runs offline, but it still helps to agree on handling accidental taps before the first move. You can return to the getting-started guide for the basic start-and-switch flow.
Pick a sensible time control
Use the preset named by your organizer whenever one is available. Otherwise, choose the base time and increment together. A very short base time with a large increment changes the rhythm of the game; a longer base time with a small increment is often easier for casual training. The time-controls overview explains the common notation and helps you compare a Fischer setting with rapid or blitz formats.
Before the real game, make one practice move on each side. Confirm that the increment appears only after a player hands the turn over, then reset the clock if needed. Once play starts, leave settings alone and use the large player panels only to switch the clock.
